awn wow 8O case the internal gear or the armature shaft should get out of alinement with themm w T- smon DEUL/TSCH, F DETROIT, MICHIG- AN.

To all/whom it may concern: i

. Be it known that I, SIMON DEUTSCH, a citizen of the United States, and a resident of Detroit, in thecounty of Vayn' 'e and State of Michigan, have invented a new and Improved Motor Gearing and Housing, of-

whichthe following is a specification.

This invention relates to means for trans,- mitting the power of 'the armature shafts of electric motors at reduced. speeds, and its object is to provide a housing and gearing within the housing which shall be composed of the fewest number of parts; shall be eniary housing comprising a headif. and a;cy-'

lindrical portion 3 by means of screws 4. A

tirely inclosed inthe housing; and shall occupy the'least possible space.

This invention consists-in combination with a shellror'housing connected to the housing of an electric motor of a plurality of stationary shafts, pinions revolubly mounted onsaid-shafts, an internal gear with which the piriions are in mesh, a sleeve connected to said internal gear and revo- -.luble in the housing concentric with the armature shaft of the motor, and a inion on the armature. shaft meshing with t e pinions on the stationary shafts. This invention further consists in forming the internal gear with which the 'inions on the stationary shaft are in mes of two parts so that there .will be no' binding in housing.

In the accompanying drawings Figure 1 is an elevation of a motor' housing and a central longitudinal section of the auxiliary housing and the gearin within. Figs. 2 and-3 are sections on the line 2-3 of Fig. 1, Fig. 2 looking toward the left, andFig. 3 toward the right. v

Similar reference characters refer to like parts throughout the several views.

This gear housing and the parts contained therein are attached to thehousing of an electric motor, and are especially adapted for use inelectric starting devices for internal combustion engines. To the housing 1 of the motor is secured a cup-shaped auxilcylindrical bearing 5 on the head 2 may. be provided with a bushing 6 in which is -revoluble a sleeve or thimbl'c 7. This thimble may be provided with an antiiriction bushing 8 in which the outer end of the arma- MO'I'OR GEAR-ING AND HOUSING.

'qecured to the armature "shaft. 9 is a pinion 13 'which-mesh cs with a plurality'of idler P11110118 14 mounted on the stationary shafts 15, carried by the head 12 of the housi; Colla' nonthe ends-of these shafts prevent the pi $14 from moving endwise, and if desired, these pinions may be provided with anti-friction bushings 17. livvolubly mounted in thecylinder 3 of the gear housing is an internal gear 18 which meshes with the pinious 14,011 the shafts 15. flvsYI-Ii'te 'nal gear 18 is made to loosely fitthe cylinder 3 and is provided withtecth 19 along one edge, suchas shown in Fig. 2. These teetl1-19 mesh. with the radial teeth 20 onthc disk 21, which disk is secured to the thimble 7 in any desired manner, pins 22 preferred. i

By the use of the pinion 13 and the internal gear 18 of unequal diameters, the speed of the two will be in inverse proportion to the diameters of their pitch lines, and the speed of the wheel 10 may be onefifth of that of the armature and even less, if desired; This isan important factor in starting devices for automobile engines where heavy torque is desired.

Should the bushing 6 in the hinge 5 wear in such a manner that the thimble 7 is out of alinement with the cylinder 3 and the internal gear 18, then the teeth 19 and 20 on the gear 18,and the disk 21 will permitthi'sdisk and gearto adjust themselves to the varying conditions,.a-nd thus prevent any possible binding and the resulting excessive friction. any portionof the"supportingmechanism by means of bolts passing through the feet 24. Power may be transmitted from the toothed wheel 10- by means-of any desiredwonnections. The sizes'of the teeth'19 and 20, their-number, and -the proportions of the different parts, may all be changed by tfhose rom.
